Azure health check — VM status, resource count, alerts summary. Returns a 100-point score.
AI agents call az_health_check to retrieve information from RedisNexus without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and reports status information about Azure resources without modifying, deleting, or executing operations on them. It is a read-only monitoring/intelligence tool that gathers existing health metrics and aggregates them into a score.
From the tool's definition Tool description explicitly states it 'Returns a 100-point score' and performs health check operations (VM status, resource count, alerts summary) which are query/monitoring operations with no modification or deletion of data.
Attacks that exploit this kind of access
Azure health check — VM status, resource count, alerts summary. Returns a 100-point score. It is categorised as a Read tool in the RedisNexus MCP Server, which means it retrieves data without modifying state.
Register the RedisNexus MCP server in PolicyLayer and add a rule for az_health_check: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches RedisNexus. Nothing to install.
az_health_check is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the az_health_check rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for az_health_check. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
az_health_check is provided by the RedisNexus MCP server (rajkumar-madhu/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
